3D Printing is for so much more than just making brightly colored plastic pieces of crap

Cute, a red Groot...but so what?When you first start learning about 3D Printing you'll usually find yourself looking at a bunch of brightly colored plastic busts. The first 3D printed thing I ever saw was a florescent green Yoda head. First you're like "HOW DID YOU DO THIS?" but quickly you're more like "OK, how many brightly colored plastic pieces of crap do I really need in my life?"

At this point you've likely dismissed 3D Printing as the world of the rich, the insane, or the nerdy, or all three. This is where I was.

I thought a 3D Printer was a $2000 thing, and of course, that's a heck of a lot of money. But I wanted to get into 3D Printing because I'd started to talk to some more advanced folks locally here in Portland and they assured me that it was cheaper than I thought and more useful than I thought. I got a $599 Printrbot Simple Metal from Amazon. You can also get a kit and assemble it yourself for $539 but the assembling is kind of hard work.

Later as I was having so much fun I got a Dremel 3D Printer for $899 also off Amazon and it's been absolutely reliable and super fun. I now consider the Printrbot a great "prosumer" hobbyist printer for folks to tinker with and improve, but the Dremel just prints, and it prints well. I had it printing well within 10 minutes of unboxing it. Both of these printers are great, but the Dremel (in my experience) has required less adjustment.

I've learned three things. They are perhaps obvious to you, but they have been amazing for me and my sons as we learn more about 3D Printing.

Lesson 1 - You can upgrade your 3D Printer

There's a great website called Thingiverse that is filled with models that others have made or remixed. You can join in and just download, or, ideally, create your own models and share. I've used Tinkercad with the kids to create new models.

One of the great jokes in 3D Printing is that people with printers never print anything useful, they just print upgrades to their printers. When you are getting started, this is actually kind of true. I took my PrinterBot and printed a base, a spool holder (figuring out where to safely and reliably hang the spools of plastic filament is a big problem.

11007949_1408985906069162_1188772249_n

The Dremel has a top lid and usually you'll have the filament inside on a special plastic spool holder. However, if you use larger or non-Dremel filaments you'll want a reliable "big spool" solution. There's a "system" at Thingiverse called the "OmniStand" that you can print that will literally replace the internal one. You can also print an OmniStand for the top of the printer (as seen in this picture below) that will let it print off very large spools.

12393609_1031042666937707_572014215_n

These were small but significant victories. This was a reminder to my sons and I that we could change these devices and make them work how WE wanted, not necessarily how the they were designed.

NOTE: You can also upgrade the Nozzle in your printer. Later I'll talk about "exotic" filaments that can give amazing results but are also more abrasive and can wear out the stock nozzles that come with your printer. I upgraded the nozzle on my Dremel for just $14.99 using this Brass Nozzle from Proto-Pasta and was able to make the swap and get back to printing in about 20 minutes, not counting the feeling of accomplishment.

OK, so you can print things to make your printer work better, cool...what else?

Lesson 2 - There are "exotic" plastic filaments that are game changers

There's a local small business just over the river in Vancouver, Washington called "Proto-Pasta." They a company of just three people that started as a Kickstarter two years ago. They sell "exotic" plastic filaments that have additives and properties that take your prints out of the "bright plastic crap" category and into something more interesting.

They have a filament with added Carbon Fiber that has created some of the smoothest and most amazing prints I've ever made. It doesn't gain strength with this addition, but rather rigidity. They have a Stainless Steel filament that is great for making jewelry or robots or anything that you want to have the heft and feel of steel. They've even got a filament with Iron so your prints can react to magnets.

I've used their High-Temperature filament that starts out clear but you bake it (literally, in your oven) afterwards and it'll shrink slightly and get VERY hard and turn opaque.

More recently I've been trying a filament with added Pine (yes, wood) that not only smells great but looks amazing with wood flecks inside the filament.

I've made dishes, vases, pieces of art for shelves, and geometric shapes for gifts this Christmas. Each one is VERTY different just by changing the filament. It's been more than changing color. These exotics change the texture and weight, and by making small changes in the software you can make them thicker or, in my case, thinner and more translucent.

I hope the folks who get these for Christmas appreciate the work and thought that went into them.

Lesson 3 - You can print parts and then assemble things using bolts, glue, etc.

This one may be obvious, but you don't have to do everything with plastic. My 8 year old and I are slowly making a "T4 Quadcopter" designed by Brendan from New Zealand (a reader of this blog) and this project will require not only lots of printed pieces but assembled pieces. You can super glue, screw, bolt, zip-tie and snap 3D printed parts together. I've been surprised at how string these parts can be when they are combined. This quadcopter will be held together with small metric nuts and bolts and zip-ties as well as some very clever snaps built-in as part of the 3D Printed model.

We are having a blast with this family hobby. We've fixed things around the house, made art, explored material science, thought about geometry, and learned about how software and hardware work together to create something bigger. Are you getting into 3D Printing?

I now want a 3d printer just so I can upgrade it. Hah, sounds like fun.
Monday, December 21, 2015 8:26:41 AM UTC
I've been wanting a 3D printer for a while, but have struggled to justify it for the "brightly colored plastic pieces of crap" reasons. I have a few uses I would want it for, I'm making some replica props but that's not going to justify a printer on it's own.

Maybe I'm on the wrong path, I could use this to start teaching the kids more about using materials and making. A turn key hassle free printer like the Dremel would be a massive boon here.

Great post. The title of your post captured the feeling I had regarding 3D printing, but I may reconsider based on some of your points.

Small typo: I've been surprised at how string these parts can be...

"3D Printing is for so much more than just making brightly colored plastic pieces of crap"

I'm not convinced, much as I like technology I can't help thinking this is a time and money sink providing very little in return.

Hi, I recently bought a Sunhokey Prusa I3 DIY kit and it's so much fun. Both to assemble (makes you understand the basics of how a printer work) and to use. There is a lot of calibration ahead using this approach but on the other hand it's fun making seeing the quality improve.
I do recognize the "just printing improvements to the printer" jokes, I've get them every day :)

Still can't think even one thing to 3D print that justify buying this tool. Your point it's that it's a good for learning and family get-togethers?
Monday, December 21, 2015 6:30:10 PM UTC
There are two camps of people around 3D printers. The ones who love them and the ones who have no use for them. I am trying to think of things I want to print and *be useful*. I can't think of anything. I don't collect figures and stuff. I will spend my money maybe on a nice follow-me video capturing drone.

Scott, you haven't answered the million dollar question- does your WIFE think the things you print are useful or just plastic pieces of crap?

I'd probably buy one if I had the spare dough, but what's the ongoing cost for materials? What you you estimate the cost to be of some of your examples, including waste and trial-and-error?

I still can't see any real practicality here personally.

I get that it's fun for you and family (kids) to teach/build though! Looks like you've made some unique stuff...make on!
Monday, December 21, 2015 10:07:57 PM UTC
Wow, this is uncanny. I saw an article yesterday about 3D Printing and I was thinking how cool it would be if Scott Hanselman did a kinda 101 on 3D Printing, seeing as I knew he'd been tinkering with it, and here the article is.

I'm thinking it would be awesome if I won the lottery as well. Let's see if that works as well as the 'wishing for article' did.

You can print Minecraft worlds which allows kids to get their worlds "for real".

3Dslash is another fun Minecraft-like 3D modeler that works great with kids.

Maybe it's worth it when you have kids, for the educational value, but I like being a minimalist. I like building the 'brightly coloured pieces of crap' in my own head or in my laptop, where I can just dispose with them when I'm done. I'm waiting for something like the HoloLens, which will hopefully give me the best of all worlds: 3-D (-seeming) objects that can be built up and then deleted at will without cluttering the house.

hi scott,
thanks for sharing! looks cool. I live in India and am looking forward to when these get under $ 500. Today, I can't afford a hobby more expensive than that.

Scott : BTW, is your 2015 power tools post ready ? thank you.

I feel like printing out a whole heap of Legos after reading this, don't ask me why.
Tuesday, December 22, 2015 10:09:40 AM UTC
What about starting with the question :"do i need this tool ?".
After that, instead of buying a 3d printer,you can just make it by your own with all the RepRap.org community you forgot to mention !
At this point you can also forget about Thingiverse, the website who stole a lot of work from the reprap community.

Last but not least, when you will use your RepRap, find a way to use some recycled filament. There is also a lot of people making recycling machine !!
Tuesday, December 22, 2015 11:15:04 AM UTC
Definitely agreed.
people said "what do I need this for" in the past for so many things, from cars, audio/color in movies and TVs to VCRs, microwave ovens, personal computers, the internet, the iPad... and so on

3D Printing is not only fun, educational, sustainable and a great family activity, it is also an amazing new way to consume products you would otherwise not buy or pay expensive for.

We have today over 1400 products on 42 categories.. all useful, functional 3D printable products. even when they are brightly colored :)

Hi Scott!
Your prints are amazing - but how did you learn to model?
Did you make your own models?

I can't wait to get one and start printing parts to build functional robots, flying devices or even some cool collectable toys.

Great article. Your title is so dead on - Ha! As technology gets better, 3d printers will be seen in more homes. The printers need to do more and be cheaper and the software needs to be more consumer friendly. Another great site to download mostly free 3d printables is Pinshape

Awesome to see the Mini T4 prints in lesson 3. I hope you get the time to put it together and have some fun! Best wishes to yourself and your family for the festive season from New Zealand.

Cheers, Brendan.

Do you have suggestions on how to scan a real object to get a 3D model to modify and print?
Eric
Tuesday, December 29, 2015 3:06:26 AM UTC
Questions of utility:
- Can it manufacture a current commercial product for cheaper than the product? Not a toy, piece of art or other decoration.
- Can it make a replacement part for a broken X?
- Can it make a multi-piece object as individual parts and assemble it into the final object?
- Can it make a useable sounding musical instrument such as a harmonica, recorder or small multi-holed whistle? (Precision of final output)
This last one would be a good test of precision since one could measure the sound quality and accuracy of the final musical instrument.

Scott, Your articles about your 3D printer and my son finally pushed me over the edge. We bought this kit on black Friday and my kids and I built it over the holidays.

http://www.seemecnc.com/collections/3d-printers/products/rostock-max-complete-kit

After many hours to build and calibrate, it is exceeding my expectations.

I think you would like this print: http://www.thingiverse.com/thing:201097

I'd like to share three things that have helped me make some amazingly precise and elaborate designs for my 3D printers.

1. A free app called OpenSCAD (www.openscad.org). It allows you to create solid 3D designs with a declarative C-style language that is very easy to learn. You can make designs that are crazy precise (any fraction of a millimeter) and parametric, meaning that you can incorporate variables that you can later change the value of, and your whole design will change appropriately.

2. Digital calipers. I didn't know these existed, but now that I have a pair I can make incredibly precise measurements of real-world objects (think circuit boards, bolts, etc), then use the measurements in my designs.

3. A Flatbed scanner. I already had one, but it took me a while to realize that I could place any part with a flat surface on there and retrieve a 600 DPI representation of its footprint. I used this, for example, to design a new backing for a Super Nintendo controller that fit perfectly with the arbitrarily shaped front half of the case.
